Government has been radically transformed over the past few decades. These transformations have been mirrored in, and often prefigured by, changes in the governance of security - mentalities, institutions, technologies and practices used to promote secure environments. This book traces the nature of these governmental changes by looking at security. It examines a variety of related questions, including: * What significant changes have occurred in the governance of security? * What implications do these changes have for collective life? * What new imaginings may be needed to reshape security? * What ethical factors need to be considered in formulating such new imaginings? The authors conclude bringing together descriptive, explanatory and normative considerations to access how justice can be conceived within the governance of security.
